Embodiment 1

[0011] The present invention utilizes Lactobacillus plantarum to prepare the concrete steps of fermented liquid complete feed as follows:

[0012] 1) Preparation of seed liquid: inoculate Lactobacillus plantarum UR-3 into the prepared sterilized MRS liquid medium, ferment on a shaker at 160-180 rpm at 26-33°C for 2-4 days, and absorb 2-4% of Strains, transferred to another bottle of freshly prepared MRS liquid medium, fermented on a shaking table at 26-33°C at 160-180rpm for 2-4 days, and finally made Lactobacillus plantarum seed liquid, the number of live bacteria in the seed liquid was ≥1×10 9 cfu / mL;

[0013] 2) Raw material pretreatment: pulverize the full-price feed raw materials and fully mix them evenly, finely pulverize the mixed raw materials to a particle size of 60 mesh, and make fermented liquid feed dry powder materials, and ferment liquid feed dry powder materials according to the water-to-material ratio of 1: The ratio of 2 to 3 is mixed evenly, and added to th...

Embodiment 2

[0016] 1) Preparation of seed liquid: inoculate Lactobacillus plantarum UR-3 into the prepared sterilized MRS liquid medium, ferment on a shaker at 30°C at 170rpm for 3 days, absorb 3% of the strain, and transfer to another In the newly prepared MRS liquid medium in the bottle, ferment on a shaker at 30°C at 170rpm for 3 days, and finally make Lactobacillus plantarum seed liquid, the number of live bacteria in the seed liquid is ≥1×10 9 cfu / mL;

[0017] 2) Raw material pretreatment: corn 50%, soybean meal 20%, puffed soybean 19.01%, whey powder 3%, imported fish meal 3%, soybean oil 1%, lysine 0.12%, methionine 0.12%, salt 0.15%, stone powder 1.1%, 0.5% calcium hydrogen phosphate and 2.0% of the premix are pulverized and fully mixed, and the mixed raw materials are finely crushed to a particle size of 60 mesh to make a fermented liquid feed dry powder material, and the fermented liquid feed dry powder material is pressed into water The ratio of 1:2~3 is mixed evenly, and then...

Abstract

The invention relates to a preparation method of lactobacillus plantarum fermented liquid complete feed for piglets. The preparation method can effectively solve problems in the prior art such as highpiglet feeding cost, poor gastrointestinal health of weaned piglets, high diarrhea rate, poor palatability of traditional dry materials, and low nutrient utilization. The method includes: inoculatingLactobacillus plantarum into prepared liquid complete feed with an inoculum amount of 4 to 6%, and fermenting at 160-200 rpm on a shaker at 26-33 DEG C for 3-6 days to obtain the lactobacillus plantarum fermented liquid complete feed. The lactobacillus plantarum is an excellent strain suitable for fermenting the liquid feed, can effectively inhibit growth and propagation of mixed bacteria and harmful bacteria in feed raw materials, and ensures good fermentation of the fermented liquid feed. The method is simple in process for preparing the fermented liquid feed, is easy to operate, particularly has an obvious effect on growth performance of piglets, and is an innovation on the fermented feed.

Description

technical field [0001] The invention relates to the technical field of fermented feed, in particular to a method for preparing a liquid complete feed fermented by Lactobacillus plantarum for piglets. Background technique [0002] In recent years, domestic food safety incidents have occurred frequently, especially the abuse of antibiotics has caused drug residues and bacterial resistance, which have seriously threatened food safety and human health. Feed safety has also attracted more and more attention from the state and society. Microbial fermented feed, as a new type of green and environmentally friendly feed, has brought new research ideas to us humans. Therefore, under the new situation of advocating food safety and green farming, we need to vigorously develop fermented liquid feed to ensure the safety of meat food from the source. [0003] Fermented liquid feed (Fermented liquid feed, FLF) is through artificially controlled fermentation conditions, beneficial microorga...
